Mr. Macgregor, of the _Rob Roy_ canoe, traversed the upper part of the Jordan, and arrived at certain measurements, which have been corrected slightly by the Palestine Survey Commission. From the source to the Dead Sea it is 200 miles long. The source of the tributary of the Hasbany is 1,700 feet above the level of the sea. The Dead Sea is 1,292 feet below the level of the sea. The Lake of Tiberias is 682 feet below the level of the sea. The river at first runs 20 miles, then falls into the basin of Hooleh, 4 miles long; then runs 10 miles, and falls into the basin of Tiberias, or the Lake of Galilee, 12-1/2 miles long and 8 miles wide; then runs 65 miles, and falls into the basin of the Dead Sea, 47 miles long and 10 miles wide. The Dead Sea is 1,278 feet deep at its greatest depth; the Sea of Galilee is 165 feet deep at the greatest; Hooleh about 15 feet deep. The Jordan ranks in size with the Dee of Aberdeenshire, but is rather less rapid. The Jordan has nearly the same rapidity as the Clyde and the Tweed. The Dead Sea, called in the Old Testament the Salt Sea, has no outlet to the south, but gets rid by evaporation from the surface of all the water poured into it. This is said to be the most remarkable depression of the kind on the face of the earth. There is no port, and there are no fish. The waters of lakes which have no outlet, such as the Caspian, the Sea of Aral, Lakes Balkash, Van, Uramiah, and the Dead Sea ultimately become more or less saline. The excessive saltness of the Dead Sea is represented as 24·57 lbs. of salt in 100 lbs. of water; while that of the Atlantic is only 6 lbs. of salt in the same quantity. THE SEA OF GALILEE.
